s ball-cechi va'lveijfor useV in connectionwith the water.suiplyY Qta t1ushingA tank;L It is Y t'o be understoodg however, that ldoVV not restrict' myself.` torf any1 particularV use of my `invention byl disclosing the` saine: in. connectiorrlwith ai flushing tank, such disclosure being for illustrative purposes only.

The objects of: the invention aret'o provide an improved valve which; will automati'cally close with' then pressure of the water;

to provide novela` and eective meansffor opening said valvegeto reduce` the pressure of water as it passes; through` the valve and 1 prevent the flow of water from being heard;

to cushion thezliowotv water: and spread the" discharged water.l into' a iifhn;` to secure simplicity .ot construction andop'eration, and toi obtain other advantagesl and results: as;

may be brought out in the following description. Y

Referring to' the accompanying drawings, in which like numerals of: reference indicate the same partsthr'oughoutzthei several views, Figure' l-is a vertical` sectionalview of a tank. showinga valve embodying my invention mounted therein;-

Fig. 2 is a vertical longitudinal section through said valve of- Fig'. 1 upon an enlargedfscale, and V F'g. 3 is a similar Vsectional. viewf showin ga modi'ed construction. of: valvel In. the speciio embodiment fot the. invention illustrated more especially in Figs., 1

and 2` of the drawings, .the reference numeral 1` indicates a tank ini theY bottom@ of which; myim-provedy valve. `is; shown mounted.` Said valve provides at its .bottom-' ani attaching member or coupling y 3, [preferably cylindrical, having aL peripheral angeft atitstop and being screw-.threaded frenaits,l bottom upward to receive a nutv 5. app ropriateA hole -ismade. inthe bottom 2 otgthetanle and the coupling 13 insertedl in vthe samewith .ther Hange- 4; -uponthe;A insideg` and the threaded portion" protruding upon` the; out? side'. The nut 5 is then applied to. clamp i the flange t to the bottom; 2 of the tank.

Furthermore, said coupling is hollow, providing therein a valve `chamber 6, and screwed into the top of this chamber is a nipple 7; the lower end o if which depends within the. chamber 6 providingat its lower extremity a downwardly facing 'val-ve' seat 8. At its upper end this nipple 7 is: extero-rl-y screw-threaded,- and receives an upwardly extending shell or tubular dischargenozzle, 9.

A; movable cap 10 overlies the: open upper endof the nozzle 9. and depending from said capcentrally within the no zwzle` is` a rod 11,

`saidrod extending` alsothroug-h a central` longitudinal aperture 123 inthe nipple 7. As shown, this s aperture 12 extenjds upwardly through the valve seat 8 `and for its `lower portion` provides a restricted passage 13 of'only slightly greater diameter than the diameter ofthe rod, said aperture 12 widening at its upper portQn and providing an` enlarged passage 14; Obviously, therefore,- wate'r may vowiVA upwardly through the valve seat around therod-V 11 within the restricted passage 13 into theA enlarged passage 14.

In order to; stop the flow, If provide,V a ball or other valve 1,5 adapted to, seat upwardly against said valve seat 8 of the nipple 7 and closethepassage 13 therethrough, rlhis s ball may be of any suitable material, but is preferably light and suthciently elastic to eiifect a tightclosur'e against the seat. I have found rubber answers these requirements very well, butlado' not restrictmyself tothe use of this` or any other specific material. The flow otfwater upward toward the passage 13 .normally carries the ball-15 againstits seat 8j with considerable energy, and the rod 11 which normally protrudesa distance through said' seat will be pushed upward bysaid ball at the proper time and the cap 10` raised.

In? orderto preventY the water from` leaving theta-nk when; the pressurein the supply pipe decreases, I4 provide` a bottomlG ,toA the chamber 6 containing-the ball orwvalve 15, and through said bot-torn` provide ahole 17 for admittin-g the water but too small to allow the ball to` passdownward into;` thesupplypipe. When the .pressure above the ball becomes greater than the `pressure of supply, therba-ll will drop downto thebottom 16 and in the shell or nozzle 9 a plurality of holes with said cap.

lodge in the hole 17, thereby preventing any back iiow of the water.

Depending peripherally downward from the cap 10 is a sleeve 18 which surrounds the shell or nozzle 9 and terminates adjacent its bottom, said sleeve being shown as integral Furthermore, the sleeve is enough larger than the shell to provide a narrow annular discharge passage 19 therebetween, which opens downwardly. it will benoted that the sleeve 18 terminates near the bottom of the tank, and as there is always a little water left in a flushing tanlr, l have ar "anged that the lower end of the sleeve remain immersed at all times.` The water issuing from the discharge passage 19 will be film-like and will intermingle with the water in the tank without the usual noisy disturbances'accompanying this operation in other devices.

ln order to admit the water from the interior of the shell 9 to the discharge passage 19, l provide a circumferential series of apertures 20 in said shell preferably near its top. As the pressure of water becomes too great within the shell, the cap 10 will be lifted, which operates to allow the ball to approach its seat and partially or entirely shut oft the flow, thus reducing the pressure within the shell. Obviously, substantially even pressure of water as it discharges into the tank will be maintained. l also provide 21 adapted to admit small streams of water into the discharge passage 19 near the lower end of the sleeve, said streams being directed transversely against said sleeve at various circumferential points so as to balance the same and prevent chattering thereof.

Extending upwardly at the side of the 4shell or nozzle 9 is a 'post 22 shown in the drawings as secured to the flange and terminating at its top opposite the cap 10. Pivoted to the upper end of this post and arA ranged to swing downwardly into a slot 100 in the top 101 of said cap 10 is a transverse lever 23 providing an arm Qil to which a balancing weight 25 is aiixed. Said weight is shown herein as a small ball screwed upon a carrier 26 which may be clamped by a set screw 27 at any desired position along the arm 2li. Preferably the end of the arm 9A is threaded to also receive the ball, if desired. v

In operation, the weight 25 is arranged upon the lever arm 24 at such a point that its moment in air will be sufficient to maintain the cap l0 and ball or valve 15 depressed against the pressure and flow of water, but, when immersed, said weight has not a sufficient moment to withstand the lifting effort of the ball or valve 15, so that the valve will close against its valve seat and stop further flow of the water` Although I much prefer to close the' valve as above described with the pressure, l can also adapt my valve to close againstthe pressure, as shown-in".l `ig.l 3 of thedrawings. Here, as in the preferred construction,

my valve provides a hollow coupling 2S at its bottom into which screws a nipple 29 having at its lower end a central restricted passage 30 which widens at the upper end of the. nipplev into an enlarged passage 31. Through these passages 30 and 31 extends a rod 32 as before, which depends from a cap 33 at the upper end of a nozzle 34 upon the nipple, said cap having af sleeve` 35 loosely surrounding said nozzle.

Within the enlarged passage 31 `and upon the rod 32 is a washer 36 of less diameter than said passage andpre'velted from moving upward on the rod by any suitable means, such asv a transverse pin 37 in the rod` just above thewasher. With the rod and cap in their lowered positions, this washer is arranged to fit downwardly over` the restricted passage 30 and prevent the water. from flowing into the enlarged passage. For holding the cap down whenthe tank is full, l pivot a lever 38 intermediate of its ends, as at 39, to a post 40 at the side of the capa one end ofsaid lever having a slot and pin connection with the cap and the other end being equipped with the usual hall float (not shown) common in the art.

-ln my improved construction a refill tube is preferably mounted on the top of the cap, as shown in Fig. 1, communicating with the interior of the cap and therefore with the flow of water through the nozzle. This refill tube 55 is thus 'removable with thecap, and can be taken` out `for examination or repairs with great ease and facility.

Obviously detail modications may be made in manufacturing my improved valve without departing from the spirit and scope of the invention, and l do not wish to be understoodas limitingmyselfexcept as re quired by theV following claims whenconstrued in the light of the prior art.

Having .th-us Ydescribed the Tinvention, what l claim is 1. ln a valve, the combination of anozzle, means for admitting a flow of water to said nozzle and for stopping said flow, a cap for the outlet end of said nozzle, a sleeve dependin, from said cap around the nozzle in substantially'parallel relation thereto and Vproviding between itself and the nozzle a said -nozzle and for stopping said flow, a y

cap `for the outletend of said nozzle,a sleeve dependlng from said cap around the nozzle in substantially parallel relation thereto and providing between itself and the nozzle a discharge passage of constant cross-sectional area, said nozzle having a plurality of small holes in its side near its inlet end arranged in a circumferential series through which water may flow to engage and hold the free end of said sleeve away from the sides of the nozzle so as to prevent the same from chattering.

3. In a valve= the combination of a nozzle7 valve means for admitting a flow of water to Said nozzle and for stopping said How, a cap movable toward and away from the outlet end of said nozzle, a rod carried by said cap and extending through the nozzle for operating said valve means, a sleeve vdepending from said cap around the nozzle of the nozzle so as to prevent chattering.
